AMD Radeon 820M vs NVIDIA GeForce RTX 4070 AD103 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct benchmark scores for either the AMD Radeon 820M or the NVIDIA GeForce RTX 4070 AD103. Both entries show zero recorded benchmark results and zero average benchmark scores. The head-to-head benchmark table is empty, meaning no direct comparative measurements exist in the database for these two parts.

Both GPUs sit at the 50th percentile against all GPUs in the database. This percentile value indicates the relative standing of each product within the full database population, though without actual benchmark scores, the percentile cannot be interpreted as a performance advantage for either side.

The Radeon 820M delivers 716.8 GFLOPS of FP32 compute throughput. The RTX 4070 AD103 delivers 29.15 TFLOPS of FP32 compute. Converting the Radeon figure yields 0.7168 TFLOPS, meaning the NVIDIA part provides roughly 40.7 times the raw FP32 throughput based on the recorded specifications. This is a specification-level comparison, not a measured benchmark result.

Pixel throughput shows a similar gap. The Radeon 820M sustains 11.20 GPixel/s, while the RTX 4070 AD103 reaches 158.4 GPixel/s. The NVIDIA GPU outputs approximately 14.1 times the pixel rate. Texture fill rates differ by a factor of about 20.3, with the Radeon at 22.40 GTexel/s and the RTX 4070 AD103 at 455.4 GTexel/s.

Memory bandwidth presents the largest ratio. The Radeon 820M uses system-shared memory with bandwidth listed as system dependent, so no fixed number exists for comparison. The RTX 4070 AD103 delivers 504.2 GB/s over a 192-bit bus with 12 GB of GDDR6X memory. The absence of a fixed bandwidth figure for the Radeon prevents a direct numerical ratio.

Where Each One Wins

The Radeon 820M wins in power efficiency by specification. Its 15 W TDP compares to the RTX 4070 AD103's 200 W TDP. The Radeon also uses no power connectors, while the RTX 4070 AD103 requires a single 16-pin connector and a suggested 550 W power supply. The Radeon's integrated form factor occupies no slot width, listed as IGP, whereas the RTX 4070 AD103 is a dual-slot card measuring 240 mm in length, 110 mm in height, and 40 mm in width.

The Radeon 820M holds an advantage in fabrication process. It uses a 4 nm process at TSMC, while the RTX 4070 AD103 uses a 5 nm process at the same foundry. The Radeon also carries a newer release date of February 28, 2025, versus February 29, 2024 for the NVIDIA part.

The RTX 4070 AD103 wins in every compute category. It has 5888 shading units against 128, 184 texture mapping units against 8, and 64 ROPs against 4. The NVIDIA GPU includes 46 ray tracing cores and 184 tensor cores, while the Radeon has 2 ray tracing cores and no tensor core listing. The RTX 4070 AD103 carries 12 GB of dedicated GDDR6X memory with 504.2 GB/s bandwidth; the Radeon relies entirely on system-shared memory.

The RTX 4070 AD103 also wins on production status clarity. It is listed as end-of-life with a successor in the GeForce 50 series, while the Radeon 820M remains active with no successor recorded.

Architecture Differences

The Radeon 820M uses the RDNA 3.5 architecture on the Krackan Point 2 chip, belonging to the Navi III IGP generation for Strix Point Mobile. The RTX 4070 AD103 uses the Ada Lovelace architecture on the AD103 chip, belonging to the GeForce 40 generation.

Transistor counts differ sharply. The RTX 4070 AD103 packs 45,900 million transistors onto a 379 mm² die, yielding a transistor density of 121.1 million per square millimeter. The Radeon 820M lists its transistor count and die size as unknown, so density cannot be calculated.

The Radeon 820M integrates its GPU into the processor package, as indicated by the IGP slot width and system-shared memory. The RTX 4070 AD103 is a discrete dual-slot card with its own memory subsystem. The Radeon's base clock runs at 400 MHz with a boost clock of 2800 MHz. The RTX 4070 AD103 has a higher base clock at 1920 MHz but a lower boost clock at 2475 MHz. The Radeon's boost clock exceeds the NVIDIA part's boost clock by 325 MHz, though the NVIDIA base clock runs 1520 MHz higher.

Both GPUs support DirectX 12 Ultimate with feature level 12_2, OpenGL 4.6, and Vulkan 1.4. Neither supports a separate FP16 path; both list FP16 at a 1:1 ratio with FP32.

The RTX 4070 AD103 includes tensor cores, which the Radeon 820M does not list. Ray tracing hardware counts differ substantially: 46 RT cores on the NVIDIA part versus 2 on the Radeon.

Specification Differences

Clock speeds differ in both directions. The Radeon 820M runs at 400 MHz base and 2800 MHz boost. The RTX 4070 AD103 runs at 1920 MHz base and 2475 MHz boost. Memory clocks are system shared for the Radeon, while the NVIDIA card operates at 1313 MHz with 21 Gbps effective speed.

Memory capacity separates the two clearly. The Radeon uses system-shared memory with no fixed size. The RTX 4070 AD103 has 12 GB of GDDR6X on a 192-bit bus. Bandwidth is system dependent for the Radeon and fixed at 504.2 GB/s for the RTX 4070 AD103.

Compute unit counts show the scale difference. The Radeon has 128 shading units, 8 TMUs, and 4 ROPs. The RTX 4070 AD103 has 5888 shading units, 184 TMUs, and 64 ROPs. The NVIDIA part also has 184 tensor cores versus none listed for the Radeon.

Power requirements diverge completely. The Radeon draws 15 W, uses no power connectors, and requires no suggested PSU. The RTX 4070 AD103 draws 200 W, uses one 16-pin connector, and lists a 550 W suggested PSU. Physical dimensions apply only to the NVIDIA card: 240 mm long, 110 mm high, and 40 mm wide, occupying dual slots.

Bus interfaces differ. The Radeon uses PCIe 4.0 x8, while the RTX 4070 AD103 uses PCIe 4.0 x16. Display outputs are portable-device dependent for the Radeon; the NVIDIA card provides 1x HDMI 2.1 and 3x DisplayPort 1.4a.

Production status and release timing differ. The Radeon is active and released February 28, 2025, with the Navi II IGP as its predecessor. The RTX 4070 AD103 is end-of-life, released February 29, 2024, with the GeForce 30 as predecessor and GeForce 50 as successor. The RTX 4070 AD103 has a launch MSRP of 599 USD.

The Verdict

The data shows two products at opposite ends of the GPU spectrum. The Radeon 820M is an integrated processor GPU with 128 shading units, system-shared memory, and a 15 W TDP. The RTX 4070 AD103 is a discrete dual-slot card with 5888 shading units, 12 GB of GDDR6X memory, and a 200 W TDP.

For raw compute workloads, the RTX 4070 AD103 dominates every recorded metric. Its 29.15 TFLOPS FP32 throughput exceeds the Radeon's 716.8 GFLOPS by roughly 40.7 times. Pixel rate sits 14.1 times higher, and texture rate sits approximately 20.3 times higher. The NVIDIA card also provides fixed 504.2 GB/s bandwidth versus the Radeon's system-dependent figure.

For constrained or mobile environments, the Radeon 820M offers a lower power draw at 15 W, no additional power connectors, and an IGP form factor that occupies no expansion slot. Its 4 nm process node is one generation ahead of the NVIDIA part's 5 nm process. The Radeon also has a higher boost clock at 2800 MHz versus 2475 MHz, though its base clock is far lower at 400 MHz versus 1920 MHz.

The RTX 4070 AD103 is the only one of the two with a launch MSRP, listed at 599 USD. Production status differs as well: the Radeon remains active with a 2025 release, while the RTX 4070 AD103 is end-of-life with a 2024 release and a GeForce 50 successor.

Buyers needing maximum compute throughput, dedicated memory bandwidth, or tensor core acceleration should select the RTX 4070 AD103 based on its specification advantages. Systems requiring minimal power draw, integrated graphics, and no discrete card installation should use the Radeon 820M. The benchmark database currently holds no measured scores for either product, so all conclusions in this analysis derive from the recorded specification data.
